ACTIVATION FRAME TRANSMISSION METHOD, PHYSICAL LAYER PROTOCOL DATA UNIT TRANSMISSION METHOD, AND COMMUNICATION EQUIPMENT

Abstract

The invention relates to the field of wireless communication and applies to wireless local area networks that support the 802.11be standard. Specifically, the invention relates to a method for indicating spatial reuse parameters in an activation frame and a corresponding method for determining the spatial reuse parameter field in a PPDU, and related equipment. This method comprises the following steps: The access point (AP) sends an activation frame, in which the activation frame is used to activate the station to send an ultra-high traffic activator based on the physical layer protocol data unit (EH) TB PPDU. The station identifies, based on one or two of the values ​​indicated by the spatial reuse parameter EHT uplink UL EHT SRP and the value indicated by one or more spatial reuse parameter fields UL SRP in the general information field of the activation frame, the value indicated by the spatial reuse parameter SRP in the universal signal field U-SIG of EHT TB PPDU.STA sends EHT TB PPDU to AP. According to the implementation of this invention's implementation scheme, the spatially reusable 30-pass field of EHT TB PPDU can be established without altering the U-SIG framework structure.
